Lisa is strapped in

Her lower body twitched, her womanhood throbbing slightly with post orgasm release. The floor felt cold against her bare thighs, and her arms were shaking slightly. Diana could feel the red on her face, the vivid sensations of her climax hitting her now more than ever. Suran's fingers between her legs, teasing her relentlessly, driving her close and closer to the edge all the while she heard her twin crying out in pleasure, Amber's tongue assailing her womanhood.

Suran gestured, and Amber moved back, a look of **** on her face. Lisa lay gasping on the chair, sweat beading her forehead and body. She could only sit and watch as the manager approached, his eyes fell fully on her naked body, dwelling for a long moment on her pussy. Diana wondered if Suran was considering fucking her twin then and there. She felt a churning in her gut at the thought, and didn't know whether it was horror or anticipation. She felt she was caught up in something beyond her control now, something that she had started and could not stop. Like a pebble tumbling from a cliff, starting a rockslide, the whole thing felt totally beyond her control. Even if she could stop at any time, it didn't feel that way. Her heart was beating fast, her mind was still trying to find context for what she had been **** to do and feel. Her lungs expanded and shrank as she **** herself to breath properly.

Would Suran **** Lisa to have sex with him, right here and now? As she was tied to the chair, unable to help, unable to resist? Or...would he do something else? What if he wanted more? What if he wanted Diana as well? To have both twins, on their very first day?

"What a show." Suran chuckled, looking first to Lisa, who glared at him, and them to Amber, who looked away. She was kneeling at his feet, her mouth smeared with Lisa's juices. But deep down, Diana wondered if she was feeling a little bit thrilled. After all, she'd made the rule herself. Anyone who wouldn't get off on this wasn't here, so on some level, Amber did enjoy this.

At least, on some level.

"I hope you enjoyed that climax, Lisa." Suran went on. "Because it's the last you'll have for a while. Hook her up, Amber."

"Y-yes sir." Amber said, dipping her head even further. The brown haired woman then moved quickly to the wires and the suction pads, the ones which had so recently been connected to her. With shaking hands, she started to connect them to Lisa's body. They connected to her thighs, to her arms. One ran to each nipple, making Lisa gasp as she felt them grip her sensitive flesh. Then, the suckers which connected to her womanhood, carefully placed so as not to close her up, because next came the the rubber sheathed phallus which Amber regretfully angled so as to penetrate her womanhood. Diana could hear Lisa groan as the thick member was **** between her throbbing lower lips.

Then, the machine was switched on, and Lisa started to breath quickly, a light buzz played over her bare flesh, teasing her nerves and tingling her senses. Her lower legs tried to clench, though were held back by the binding. The machine had started to do the same, pleasuring her with a slow inevitability. But she would not be able to climax. Each time she came near, she would be shocked. A cruel game indeed, dangling her release right in front of her, forever out of her reach.

"Right, Diana." Suran said. "I suppose I should continue the tour with you now? And Amber, you can come along as well."

"Yes, sir... Can... can I put on my dress at least?"

"Hmmm, no, I don't think so. Come with me, you two. The day is just getting started."
